Subterranean bass that takes up less space

Definitive Technology's super-impressive SuperCube 8000 subwoofer will fill your room with huge, heart-pounding bass while consuming only a little valuable real estate. Driven by a brawny 1,500-watt amplifier, this compact sub's active 11" woofer and two 12" passive radiators combine to deliver low-frequency output comparable to that of a traditional 18" woofer, but with greater speed, musicality, and definition. Its versatile inputs, comprehensive controls, and handy wireless remote give you the tools you need to dial in pinpoint-perfect bass that adds visceral impact to all your movies and music.

Rock-solid bass requires rock-solid construction

The SuperCube 8000 sub uses a new class of high-efficiency amplifier to bring 1,500 watts to bear. Its clean muscle is preceded by a 56-bit DSP preamp stage that kills distortion before it ever reaches the amp, let alone your ears. The SuperCube's 11" woofer cone is encased in an incredibly rigid, cast aluminum basket engineered to hold the massive magnet structure and large voice coil in absolute alignment. The rock-solid cabinet uses front and rear panels nearly 2" thick with multiple internal braces to make sure that you hear clean bass without sound-muddying vibrations.

Flexible inputs and advanced controls

Line-level and speaker-level inputs let you connect this sub to just about any audio system. The continuously variable low-pass crossover allows you to precisely control the frequencies that your subwoofer handles. And the disappearing display lets you monitor the 8000's settings while you adjust them from the comfort of your easy chair with the included wireless remote.

Why add a powered subwoofer?

A powered subwoofer gives you bass you can feel as well as hear. Our customers love the depth and impact their subs add to music and movies. We hear comments like "it brings out sounds I didn't know existed in discs I've watched a million times." Powered subwoofers aren't just for big bass that rattles your picture frames; they can also deliver tight, accurate lows. If you haven't shopped for a powered sub in a while, you might be surprised at how small they get. Look for an ultra-compact model if you want to tuck your sub away under an end table or in a corner.

Excellent!

Pound for pound an excellent sub woofer. This supercube is an excellent addition to my home theater. I did a lot of research on this product and this fits my needs perfectly. Definitive really hit a homerun with this one. It enhances every movie that I have pitted it against. In my opinion this beats any movie theater that I've gone to. But not only for movie this subwoofer also enhances my music as well. Thumbs up to Crutchfield and definitive for excellent service. Chalk up another satisfied customer on the board.

Pros:extremely tight clean bass. Technological breakthrough in such a small form factor. Remote control enhances set up and eases control for movie/music applications.

Very Satisfied - LFE you FEAL

My room size is 14'Wx22'Dx8'H. For home theater use, the SC8000 is just right for my room size in my opinion. I would think it would be sufficient for much larger rooms as well. Passed over the SC6000 because I thought a 9" subwoofer would be worked too hard. I am completely satisfied with the power and output of this 11" subwoofer. I operate with volume at 25 normally. Set crossover in my AV receiver at 60 Hz. Sound integrates perfectly with all of the Definitive Technology DI series speakers in the system. Sounds like the hugely (but not too much) enhanced bass is coming from all 7 speakers around me. LFE sound effects in movies is impressive with this subwoofer. Sounds (feels) like the movie theater has nothing on my basement home theater (except the 150 foot screen). Great binding posts, although I only use the LFE input.

At it again.

Written By Pete M., Garrison, New York on Thursday, November 13, 2014

I'm the proud owner of a PF11500. It's about 20 years old. Not replacing but adding SC8000 to my already awesome home theater. A Month ago the power supply went on my old sub and definitive repaired it. After all this time they still care about their customer. Try that elsewhere. Crutchfield also pays great attention to their customers so it's on again.

Pros:Great performance and quality construction.

Cons:My 20 year old sub has no remote. Doesn't need it anyway. Wait, that's not a con.

Definitive SuperCube 8000

I've had the sc8000 for less than a month and am very busy so I'm still within the "break in phase" of this amazing sub. I just took my 9yr old to see the lego movie yesterday on the big screen, and for the first time ever, the theater sound reminded me of home. Normally I'm striving to make home remind me of the theater. The deep deep bass is perfect for movie soundracks and deep bass music like rap. Some obvious design flaws are the removable piano glass black top. Its meant to make it pretty but the way it sits causes it to make a squeaky vibrating soundso I removed it. The mesh that surrounds the whole enclosure also vibrates on the enclosure around the active driver due to it moving massive amounts of air. Considering removing it as well but its not that noticeable. Overall I think for my space, which is an open floor plan with living, kitchen, dining rooms all open with 15 foot vaulted ceilings, it does it's job very well.

Pros:Massive deep bass. Great for low volume, late night listening with adjustable volume. It's got so much power the rest of my system doesnt have to be cranked to get good output from the sub. The remote controll is priceless.

Cons:It's very elegant looking but that doesn't help its perfomance. Strip the cosmetic add ons and let this deep voiced mini monster shake not just vibrate you to your core.

Definitive SuperCube 8000

I have tried both HSU and Velodyne. HSU doesn't come on all the time and sounds a little heavy. The Velodyne was junk, stopped working after a couple years with little use. This subwoofer sounds better , and is easier to incorporate into my system without it overpowering everything with too much boomy bass. The remote works great, the different eq settings also actually make a difference. Really like the sub for the money. It is in my great room which is 26x30 with 11 foot ceilings , and the only time I would need more bass is when we are listening to old school hard rock.

Definitive SuperCube 8000

Replaced an older and much larger Velodyne with accelerometer control. The SC8000 is a definite step up in responsiveness and much better definition/musicality (subjectively speaking). Objectively, the SC8000 is putting out ~107db at 20hz and a measured +/- 3db down to 22hz in the Grand Room. The SC8000 has proven itself as a formidable home theater sub woofer with extremely satisfying results in a wife-approved compact package!

Definitive SuperCube 8000

I had a malfunction on a competitor's product (downfiring 12 inch) which I also purchased from Crutchfield 20 days earlier. I called Crutchfield and they cheerfully accepted my return and recommended I change to this newer compact passive radiator design. I went one up over their recommendation of the DT 4000 and received the DT 6000 which was impressive. But I just wanted something even more impressive. II upgraded to the DT 8000 and its is quite impressive. Deep solid bass tones on music and the bass on bluray movies is very impressive. I watched Lord of the Rings 3 final battle scene and when the elephants feet hit the ground on screen--my house had an earthquake like movement--made me smile with satisfaction. The next day I discovered every shampoo bottle in the two upstairs bathrooms rattled off their shelves. I'm childishly happy.

Really good output for its size

Packaging from Definitive leaves a lot to be desired. The sub weighs a remarkable 72 pounds. This sub is less than 16" on a side. So it comes from the factory in a single walled, thin walled box with only protection on the top and bottom. Unacceptable packaging for an expensive sub. It should be double boxed with protection of the sub on all sides at this price. It's a miracle it arrived without damage.

My room is 13x14x9 ( about 1650 cubic feet) and can be sealed off via 2 pocket doors. I listen with the doors closed. So far I watched 3 movies. 2 blu-ray and one Vudu HDX stream. Given my small room size the bass was impressive. The room was well pressurize even to a point of it starting to be uncomfortable (in a good way). This with the volume set at 15 and the AVR at -10 or 15db from reference. Plenty of tactile feel in the body and through the sofa.

I have no experience with any other sub in this room so I can't make comparisons. But I will say that it provides plenty of output in my room and room response is surprisingly even across the 4 wide sofa so all of the family get a great bass experience.

5 stars for its size and output in my small room. 4 starts when factoring the price and my opinion that a room larger than 2500 cubic feet might need to have near field placement for adequate response.

Pros:Great output for its size although I have nothing to compare with. Remote is great. Size is a plus.

Cons:Packaging, EQ modes not really useful. The sub sounds best with the EQ off. Not crazy about the pop off top. It comes off too easily and rattles a little. Price is pretty high.

Features

Definitive Technology SuperCube Powered Sub: The Definitive Technology SuperCube 8000 is a
compact, high-quality powered subwoofer intended for use in a music or home
theater system. The SuperCube 8000 powered subwoofer allows for easy, seamless
integration into almost any two-channel or multichannel speaker system;
delivering true, accurate, & extremely deep bass in any room. The Definitive Technology SuperCube
8000 features a 1500-watt digital amplifier, 56-bit DSP, 11" woofer with dual
12" passive radiators, & an included wireless remote control. The SuperCube 8000 is finished in a piano-gloss black lacquer finish with a black
non-removable cloth grille.

1500W
Digital Tracking Amplifier: The Definitive Technology SuperCube 8000
features a 1500-watt (RMS) digital tracking amplifier that is optimized for real
world power demands to deliver low distortion & high output. As well as
producing high continuous power to cleanly reproduce sustained bass (down to 10
Hz), this all-new Definitive Technology digital amp has a high crest factor to
deliver considerably higher power during short, transient peaks such as bass
drum kicks & on-screen artillery blasts. You'll enjoy high volume, high impact,
& low distortion bass from your favorite action/adventure films & TV shows
without sacrificing the smooth response & quick precision needed for music.

Note: As well
as being powerful, the new Definitive Technology digital amp is
environment-friendly. The amplifier goes into idle mode after less than 30
minutes of no audio signal. When in idle mode the amp draws a mere 1/2 Watt
or less of current, meeting international standards for low energy
consumption.

56-Bit Digital Signal Processor (DSP):
The
Definitive Technology SuperCube 8000 has an integrated 56-bit Digital Signal
Processor (DSP) that extends & improves the bass response. Multiband digital
protection systems tightly monitor & control the woofer system to prevent
distortion & woofer damage at ultra-high volume levels with a minimum of audible
artifacts. In contrast to simpler one-band compression/limiting circuits used in
competing subwoofer amp designs, the Definitive Technology SuperCube 8000
features a Multiband Dynamic Range Optimizer (M-DRO) that divides the frequency
range into multiple bands. If the DSP detects an overdrive condition in the
upper bass range, it applies just the right amount of compression & to prevent
distortion to just that range without compressing the low bass, thereby vastly
reducing the audible compression artifacts. As a result, the SuperCube 8000's
bass is always tight, highly detailed, & distortion free.

High
Definition Drivers: The powerful, high-definition drivers used in the new
SuperCubes were specifically engineered for their task: to deliver rock-solid
low distortion bass, reaching down to the lowest frequencies (10-200Hz), with an
outstanding quality of superior transient response ("tightness"). The special
ultra-stiff cones are joined to specially formulated surrounds & long-throw
voice coils & spiders. The incredibly rigid cast aluminum baskets are engineered
to hold the massive magnet structures & large voice coils in absolute alignment.
The high temperature voice coils are made of aluminum wound with triple
insulated ultra-pure copper wire & baked in epoxy for superior power handling &
reliability.

Passive Radiator Design: The SuperCube 8000 features an 11" subwoofer
driver pressure coupled to two 12" Ultra Low Bass Radiators. The total piston
area is greater than a 18" diameter woofer but with far greater speed,
musicality, & control than a single large diameter woofer could ever deliver.

Non-Resonant Cabinet: The
cabinet of a loudspeaker plays a large part in its sonic performance. Resonance
& vibration can add unwanted distortion as well as drain away important
acoustical energy from the system. Definitive's subwoofer enclosures have been
specifically engineered to be totally inert & vibration free, to ensure you of
absolutely pure sonic reproduction. The front and rear panels are nearly 2"
thick & the cabinet incorporates multiple internal braces to ensure total
solidity. The SuperCube 8000 is finished in piano-gloss black lacquer finish.

Interchangeable Feet: The SuperCube 8000 comes with 4 rubber-feet
& 4 spiked-feet for safe & secure placement of the powered subwoofer on
your carpet or hardwood floors. The spiked feet add approximately 0.125" of height to the
powered subwoofer.

Placement: There are some general guidelines that you should use when
locating the powered subwoofer.

For best results, place the subwoofer on the same side of the room as
your front speakers.

For maximum output, the subwoofer should be placed in a corner or
against the wall, leaving approximately 2" to 4" clearance between the
powered subwoofer and the wall(s).

Corner placement will increase the powered subwoofer's output.

An acoustic effect called "standing waves" or "room modes" may cause
uneven bass at various locations throughout the room. This phenomenon is a
function of the dimensions of the room and not due to the design of the
powered subwoofer.

Protection Circuit:To prevent accidental damage to the subwoofer from
overdriving the system, the SuperCube 8000 features an internal overload
protection circuit, which will turn the subwoofer off or down when overdriven or
overheated & will then resume normal operation after a few minutes.

Controls

Subwoofer Controls: A complete array of controls allow the
SuperCube 8000 to be perfectly integrated with any stereo or multi-channel audio
system, and tuned for optimum performance in any room.

Note: The remote operates off of a single 3V lithium battery
(CR2025).

Volume Control: The SuperCube 8000 features a rear-mounted
push-button
volume control (0-40). This control is used to raise or lower the output level of the
subwoofer in relation to the other speaker in your system.

Note: There is also a mute button on the remote control to zero
the volume level quickly.

Variable Low-Pass Crossover: The Definitive Technology
powered subwoofer features a continuous variable low-pass filter control on the
back-panel. This filter is continuously variable between 40 and 150 Hz. It
"rolls-off" (24dB/oct) the high-frequency response of your subwoofer so only
low-frequencies below the desired setting will be heard. This low-pass filter
control is used to obtain the optimum transition between the subwoofer and your
main speakers.

Variable Phase Alignment: The powered subwoofer features a
rear-panel push-button phase control (0/90/180/270-degrees). This
control is used to perfectly blend the output of your subwoofer with your main
speakers to compensate for any possible problems due to placement constraints.

EQ3: Raises the level of mid- & ultra-low bass frequencies (a
great setting for movies when not played at ultra-high volume levels).

EQ4: The best setting to use when achieving maximum volume levels
with minimal distortion is more important than reproducing the lowest
frequencies.

Night Mode: Night Mode applies dynamic range compression to the woofer
so that the loudest bass in a movie doesn't get loud enough to wake the parents,
kids, or spouse at night.

Auto Turn-On Circuit: The powered subwoofer has a special
power circuit which automatically turns the powered subwoofer on when a signal
is fed to the loudspeaker and turns it off when there is no signal present, so
it does not require an on-off switch.

LED Indicator: The red LED on the back panel of the powered
subwoofer will light up when a signal is sensed and the amplifier turns on. It
will automatically turn off with the powered subwoofer, a little while after the
signal is discontinued.

Connections

Line-Level & Speaker Level Connections: The Definitive
Technology SuperCube 8000 powered subwoofer has a complete range of inputs &
outputs to allow easy and effective hookup to any system. Both (high) speaker
level & low-level inputs are provided in case you do not have a subwoofer
output. In addition, the SuperCube 8000 has a separate direct-in LFE low-level
input (which bypasses the crossover network).

LFE Input: The LFE input on the SuperCube 8000 is a mono-RCA
input which is not affected by the subwoofer's low-pass filter or low-pass
crossover control. It is designed to connect the SuperCube 8000 to a receiver
which features a dedicated subwoofer output which features its own low-pass
crossover filter.

Low-Level Inputs: If your receiver does not feature a
dedicated subwoofer output, but does feature stereo RCA outputs, you can use the
SuperCube 8000's stereo RCA low-level inputs (which provide its own dedicated
variable low-pass crossover circuit) to connect the subwoofer to your receiver,

Speaker Level In: The Speaker Level inputs (5-way binding posts)
are designed to be used on receivers or amplifiers that do not incorporate any
RCA type subwoofer outputs. If your receiver is equipped with an RCA type
subwoofer outputs, these speaker level inputs should not be utilized.

Detachable AC Power Cord: The SuperCube 8000 includes a detachable 7'
AC power cord. The SuperCube 8000 must be plugged into a 120V, 60Hz electrical
socket (use an unswitched outlet if possible).
